.Finally Pulled the Trigger on a Dapra Biax 7EL Scraper

[LEEQ]

Looking forward to your sharpener build. I would like to see your take on making a single speed biax variable, too. Do you plan to vary the speed in your biax?

I hadn't thought of varying the speed of the Biax, but it would be an interesting idea to play with.
a router controller could accomplish the same thing i suppose:thinking:

the sharpener seems like it would be a fun project !!!

thanks Leeq!!!!

Look at the whole posting, it shows some of my other goodies. I got the gear motor from ebay for like 59, the diamond lap was 60ish and I had to buy a molex connector and I am working on mounting it on a box with the wiring inside.

Here you go... http://www.ebay.com/itm/GEAR-MOTOR-...ultDomain_0&hash=item5415359cc7#ht_322wt_1153

That link is only an example of a motor, you want around 6-800 rpm, the one I linked to was 180

Thank you astjp2!
i have a DC motor and PWM controller.
i'm thinking the variable speed would be a nice feature )

Did your biax come in yet. It looked like it may have been modified already in the eBay pic. Look at the picture showing the handle. There appears to be a thumbwheel sticking up. Bob

:ups:

the Biax came in today!!!!!!

i'll open the box and take pictures after lunch!!!!

Drum Roll Please.....!!!!!




I plugged her in and she sings like an angel !!!! She came with 7 Carbide scraping tips!!!!
i dropped a few drops of oil on the reciprocating mechanism and flicked the switch.
The unit is not variable speed, the switch in the handle is a simple on off.
there is a strange hole in the end of the drive motor cap near the plug that is puzzling me:thinking:...
the hand strap is also missing.
but otherwise it should be a serviceable tool for a while.
i'll check out the carbon brushes after dinner,
So far i'm very pleased.
i'll need some other supplies before i can dive right into scraping, but soon the scrapin' will start again!!!!!

thanks guys for reading and the suggestions,

keep em coming, i'm all ears and smiles:biggrin:
