Pump drill

We decided to go and mooch round some junky antique shops in Sawbridgeworth today and Ness spotted this pump drill . . .


Obviously that cord isn't original - anyone got any ideas on what type of bit would have originally been used ?

According to Salaman this type of drill was only used for metal, stone etc and not wood because the bit would have got bound/stuck on the return stroke.

We also bought an angle measuring gadget, a very clever boxwood corkscrew "A Present From the Seaside" and an interesting book about the History of the Rocking Chair

Use on such a drill would be a jewelers set of index bits and burs. For the index bits it best to use bees wax on the side of the bit to lubricate before drilling. Watch makers also use the pump drill because of the low speeds controlling the piercing of the material. Its slow but very clean. I'm looking for one myself. If anyone knows of someone who wants to sell one email me at gaiayn@gmail.com. Please indicate something in the subject line. Have fun with it.

Thanks for posting. I just scored one on eBay built to a very similar pattern. Have you learned anything about it since you bought it? Any luck finding bits for it?

Thanks for posting! I just scored what looks like the same model off eBay. Did you ever have any luck finding bits for it?

Sean - I sold it before the need arose...!
Think you might have to make your own bits?
