Mod. Hitachi Cut Adjustment Knob

My cut adjustment knob keeps falling out! Anybody know what that stuff was that came with the planer? It worked well for the longest so far. J&B Weld worked for about 4 months (second longest). Two part quikset epoxy no good, marine epoxy putty is a decent temporary solution. The mechanics next door have a better epoxy putty for me to try tomorrow. For some reason they didn’t think a weld would work, I don’t know enough about it, guess you can’t weld aluminum to stainless??? Just wondered if anybody out there has had better luck with something else?? I don’t know my problem, guess I just get too rude on the little thing. Anybody put a small bolt right through the depth knob?? I was considering this but don’t want to loose the nice little knob thingy. Any help would be awesome!!!

just looked at the manual on FoamEZ (that’s sweet!) didn’t tell what kind of glue it was. They call it something else, a depth adjustment indicator, just so you know what I’m talking about. It’s the little pin thingy.

3M makes an extensive line of adhesives available in tubes. The marine series are the 4000 and 5000 I believe and something like the fast set 5200 adhesive will probably work fine. Recently I bought a ladder rack for a work truck and it came with some fittings that had to be fixed to the truck bed with self tapping bolts. In the kit they included a tube of the 3M 6000 adhesive for a semi-permanent thread seal on the hardware. I’d give that one a try on your Hitachi depth control pin.

One of my Hitachis had the same curse. After about the 4th “fix” I just took some 3/4"

tape and wrapped myself a “knob” on the end of the little post. All you need is something

for your finger to ride on. Took about one pass to get used to.

No you cant weld stainless and aluminum. I think you can solder it.

Why don’t you drill and tap the aluminum and stainless together and put a few set screws in it.

Dass Funny. Hey, thanks for all the help. I have a couple other planers that have suffered the dreaded duct tape fate, trying to keep at least one ship shape. 3M 6000 is a good idea! I think that if the epoxy putty doesn’t work today, then I’m going to put a bolt throught that doughnut, then I’ll probably tape the end of that. OH well. Thanks again!!

DT,

I would check out www.cotronics.com. They have all kind of adhesives for metal repair. Not sure if they will have what you need, but it might be worth a look.

I think your problem is mostly due to trying to adhering a smooth surface to a smooth surface. Hit the metal post with a file in the area where it will insert into the knob to cut a series of small grooves. This will give the epoxy something to “key” into. You can also roughen up the inside of the knob with a nail or pocket knife.
