TopBar hive Bars

[Michael Bush]

Some bees will take the slightest hint on where to build comb, such as wax in a groove. Most, however, will need more of a hint than that. I recommend a good distinct comb guide. At least 1/4" or more deep. The triangular ones are the strongest attachment and the best followed, but a paint stick or popscicle sticks work pretty well.

All of my Top bars were cut out of 2x4's and have a wedge cut as a guide which seems to work pretty well. I get 3 bars per 2x4. I have 1 1/4 and 1 1/2 bars which seems to work pretty well also. Using 2x4's meant 1 less cut on the 1 1/2 bars.

One other technique to consider: This spring I am going to follow the advice of a very experienced beekeeper friend and set 3/4" x about 6" strips of beeswax covered foundation in the saw kerfs of my topbars, "gluing" them in place with melted beeswax. They sell devices to precisely drip melted beeswax but I think I'll make my own. Just a metal tube. You dip it in melted beeswax to partially fill, then hold your finger over the top hole like a straw, withdraw it from the beeswax and release your finger to dispense wax into the kerf. Like we all did as kids with straws. I'll let you know how it works.

I have used a combination of 1 1/4" bars for brood and 1 1/2" bars for honey, and I have used all 1 1/4" with and without spacers. I like the combination the best. I glue and brad nail strips of molding on each bar for a guide, and I rub them with dry bees wax. Gives a hint of wax that will never come off. Melted wax breaks off easily.

One mistake to avoid is making the comb guides too long, hoping to make them "fit" perfectly inside the hive body to keep them from sliding side-to-side. This is a bad way to go, as if the sides bow at all over time (and they often do) or if you want to use a bar in a different hive and it's a tiny bit different in width - the bars don't fit. Give them a good couple of inches of space on each end of your bars. I make 18" long bars with 14" long guides, and find they work perfectly. The bees will add propolis to the edges along the walls of the box and you won't have to worry about them sliding side-to-side. I have had to go back and cut down guides on some bars because they wouldn't fit in another place or another hive.

I was wondering if rope molding would work ok. It is fairly inexpensive and would save a lot of time for someone without a table saw. The profile is rounded and it would seem to have a decent amount of surface area for comb attachment.

It works fine for me. But I do use string (1mm), not rope. Wool srings may remain a bit too 'fussy' to my liking, so nylon or some other non 'fussy' string will be ok. Although they're doing great with wool strings here.
I staple the strings to the top bars, and then melt some wax on it using a soldering iron. Saw it on a youtube video. Easy as can be, cheap, and works great

With a table saw the triangle guides are pretty simple to make. Blade to 45 degrees cut a right triangle out of 3/4 stock and than cut it in half. That makes 2 nice little triangle guides that you glue and staple to the bar.

I used the groove and tongue method that a few others have mentioned. I cut a groove the whole length of the bar, not just in the needed area, because I was lazy and just ran them through the table saw. I think the tongues I used may actually be a bit too big. I cut strips of some 3/16" thick board I had, and then glued it in. It makes for about 1/2" tongue. I think this is too big, and messes with how the bees build the comb off of it. At the top of each comb they tend to attach the comb to the bar and the tongue and it makes for an odd bulge out in the comb at top, which the bees like to connect to the adjacent comb unfortunately.

I also had problems with cross combing right out the gate (I posted a thread about it) so obviously my guides were not very convincing. I also had covered them with copious amounts of wax.

I'd say the simplest thing to do is just slap in some blank top bars, and check them in the first week and correct any cross combing. Either have some hair clips, or cut-out frames available in case you do have to cut and move comb. And make sure that when you do cut and move it, that you re-attach it upright.

As a bonus, I highly recommend installing the glass window so you can look in the hive without opening it. I was able to see that my bees were cross combing, so that I didn't accidentally pull the bars apart and destroy comb. I knew I had to pull three bars all at the same time, and then carefully cut the comb loose and re-align it.

Good luck and God bless!

I probably dont have much place in posting a how too...but I will post what I think is one downfall to this style of hive and a way to remedy it, correct me if I'm wrong here....its something I'd like to try out for next year. Mind you my hives are still in packages and going in tonight lol. A local bee keeper mentioned this and unfortunatly I had my bars completed already so without redoing them applying this wasnt much of an option.


FIrst my hive isnt that big (its a golden mean hive) and due to time issues, I bought bars for both my hives. Took longer to build the hives with what time I have than I planned. Feeding in a smaller hive atleast for me seems to be a pain. The follower board style I built last night hopefully will work ok. But drowning bees concerns me.

The hive top feeders seem the be the best of both worlds. Problem with the tbh, no gaps between bars. So what the fellow I bought my bees from did, was use pan head screws and left his bars smaller in width...using the screws and a langstroth spacing tool to get the correct spacing by screwing the screws in or out on both end to get the correct gap between bars.

This allows him to use the tbh like a langstroth with the simplicity of a tbh. His hives are also set up so he can put two supers side by side on top...seems like a slick idear, though I dont honestly know how it would over winter being he doesnt over winter his tbh's. He does over winter 25 or so langstroths and atleast up here he had to make a building to over winter in due to poor success outside....

By using the gaps you can also add a host of different feeders on top, plus the supers. I dont know if you'd use a excluder or not (in his case he'd need two I would assume), I havent asked yet. I plan on making a couple more on the GM plans and stretching things out some to give this a go in a hive or two for next year. Either way it makes his gear interchangeable to a degree.

I also thought about using this method for my bars on the honey end but not on the brood chamber area for now....it would also allow me to run a hive top feeder in the mean time and keep the brood area warmer I'd think by having it completely sealed off on top. I dont have time to redo the hole hive... or really know how many bars to expect to be boord/honey. The supers he added where the deeps.

Something else I thought about in building of the bars. (I also dont like the saw kerf method...first one he picked up had the 'foundation' strip follow out along with the hole comb!).

I'm not sure but if you cant make a V bar, or are looking for a simple way to do it.....use molding if you can find it. Either glue it to a top piece or glue to the sides with the V in the middle...when the glue drys....pin it with wood dowls to ensure it never comes apart. Most V molding has a cove on what would be the flat part you'll want to remove. if you have a belt sander turn it upside down in a vise turn it on and freehand them flat. A hand plane or saw it if you have a table/bandsaw works also Than glue it on and glue/pin it together with the wooden dowels. Seems simple atleast in my head . Its what happens when you are at work for 12 hour shifts lol.

Thoughts?

Good idea on sanding down the cove molding. I was thinking I could use bar making as a justification for a table saw, but the reality is that I really don't need a table saw, and I could purchase bars for a lot less than a saw.

[Tom Brueggen]

C'mon, you can't talk yourself out of a table saw so easily...I just upgraded from a crappy little table saw that I purchase at a yard sale, to a full size model for on $550. No regrets! I know it may sound like a lot of money, but you have to weigh convenience against dollar value. Besides, I'm sure the table saw is good for more than just cutting top bars.

[shannonswyatt]

I was at Lowe's looking at the table saws thinking how cool it would be to have one of the nice Dewalt models. But I go years between using my Skil saw.

My uncle retired a few years ago and put together a really nice woodworking shop. Central vacs, sanders, band saw, routing table, table saw, rotary arm saw, planner, etc. But he never does anything out there, so I was thinking I could get him to let me use some of his tools, or to help me with this project.

[AkDan]

What I would do for a full size saw. I have a table top delta 10" that screams I want your fingers lol. No way to make a zero clearance and use the fence. Keeping my eyes peeled for a rigid contractor model. Pretty sweet saw with a good fence !

[shannonswyatt]

Well, based on your location, you may just want to go to Santa's workshop!

[Keefis]

Your uncle would be stoked I'm sure. I have a woodshop and I love it when my friends and family want to come over and make something. It gives me a reason to use my tools/talent.

I used 1 3/8 bars with popsicle sticks glued to a groove in the middle for about 5 years. They worked ok, but frequently the bees got off center and the comb crossed bars. After reading an article by Michael Bush, I tried 1 1/4 for brood and 1 1/2 for honey with the triangle piece for a guide. That really seems to be working well for me. I started 5 "nuc" boxes this spring with 9 brood bars in each. When I transferred them to a full size hive box, all the bars were straight and nicely formed. You really need to make a jig to cut the triangle pieces but a band saw makes that a not to difficult job.
